While menopause in women is a well-established and well documented phenomenon, the andropause in men is a relatively new concept. The terms male menopauseand andropausesuggest that this is an abrupt phenomenon related to a sudden deprivation of sex hormones. Unlike the menopause, which has a relatively sudden onset, the andropause appears to be a gradual process. It has been hypothesized that an androgen deficiency might develop with aging. Androgens and the Aging Male explores this hypothesis. The book focuses on the gradually progressive problems related to the decline in androgens that can occur with advancement of age. It examines the debate about the extent to which an age-dependent decline in androgens leads to health problems that affect or impair the quality of life, and the theory behind it. In addition, it reviews studies evaluating the effects of androgen supplementation. Androgens and the Aging Male comprehensively covers androgen function and how it changes over time.

Even though research on testosterone is increasing, there is still much controversy regarding its physiology and clinical use. This book provides a broad overview on testosterone, from its basic features to the most recent evidence of clinical applicability. In addition, specific conditions in which testosterone play a pivotal role are discussed in detail, such as hypogonadism, misuse and abuse, puberty, cardiovascular effects and testosterone therapy. The testes are vital organs for reproduction of the human species, besides being the main source of testosterone production in men. Although not essential for survival, these singular structures represent the essence of male biological function. Testosterone is the most important testicular androgen in men. Low serum testosterone levels are associated with cardiovascular morbidity, metabolic syndrome, type 2 diabetes mellitus, atherosclerosis, osteoporosis, sarcopenia, and mortality. Also, there is increasing evidence that serum testosterone is a major biomarker status of men's health in general. Hypogonadism in a male refers to a decrease in one or both of the two major functions of the testes: sperm production or testosterone production. These abnormalities can result from disease of the testes (primary hypogonadism) or disease of the pituitary or hypothalamus (secondary hypogonadism). Currently, the clinical features of male hypogonadism are sufficiently well-recognized, the causes are well-known, and the tests of the hypothalamic-pituitary-testicular axis are accurate enough for the diagnosis in most patients. Testosterone, the focus hormone of this book, is used in different forms and routes of administration. Several authors unravel its peculiarities and assist in choosing the most suitable form in each case, as well as the possible risks of its misuse or even abuse in men and women, seeking alternatives to help patients in this situation.

Nearly 2 million men turn 50 every year. The natural hormone testosterone promises to be a fountain of youth for them, as well as every other aging man. It can revitalize virility, slow the aging process, and even help counter impotence.

"The Secret Female Hormone is a must read for women today! Hormones should always be evaluated in unity, and testosterone is almost always overlooked. The authors tell the truth about how hormone imbalances truly affect women - not only their energy, their vitality and their libido but also their family relationships and self-esteem. This book will be a resource for women for years to come!" - Marcelle Pick, author of Is It Me or My Hormones? and The Core Balance Diet Leading experts show why testosterone hormone imbalance could be the vital connecting factor in a wide variety of health issues for women in midlife. You know the experiences all too well. You can’t sleep, so you start your day feeling exhausted. Seemingly overnight, you can’t remember names, places, appointments—things you could previously recite at the drop of a hat. You want to be more active, but you have zero energy for that. And sex? Forget it! By now, you’ve probably been told this is "normal," or that it’s the "natural" course of aging. And you might even believe it, because so many women approaching midlife have the exact same symptoms. In fact, millions of women worldwide are undiagnosed and untreated for hormone imbalance deficiency. As one of the country’s leading experts on hormonal balance—and as a woman who experienced these symptoms herself—Dr. Kathy Maupin has identified a debilitating and overlooked health condition: testosterone deficiency syndrome, or TDS. Most people associate testosterone with men, but it’s one of the most vital hormones in women, and one of the first hormones that women begin to lose as they enter their 40s. And Dr. Maupin’s own research has shown that the symptoms of aging—fatigue, memory loss, moodiness, low libido, and so much more—are initiated and accelerated by testosterone loss. In this book, Dr. Maupin and therapist Brett Newcomb show how testosterone replacement can radically improve your life. They share the history and background of hormone replacement therapy, the latest research on treatment options, as well as: • Tips for dealing with mood swings, changes in sex drive, and maintaining healthy relationships • Surprising information on the long-term effects and health risks of testosterone loss • Common myths and misconceptions regarding estrogen and testosterone replacement therapy • Questionnaires to help you determine your individual hormone deficiencies • Real stories and personal experiences Dr. Maupin’s patients share clear, practical, and easy-to-use, this authoritative guide sheds light on the importance of testosterone and will help you reclaim your physical, mental, emotional, and spiritual health.
